Two horses Paulus Potter (1625-1654)

The picture has something of this: cavalry, mammal, horse, mare, seated, livestock, equestrian, farm, pony, stallion, mustang, equine, two, racehorse, animal, outdoors, mane, pasture.
Perhaps it’s a painting of two horses standing in front of a fence with a bird flying in the sky in the background and a bird in the foreground.
